ADJUST ABLE SHADE FOR WlNDO-WS.

SPECIFICATION forming part of Letters Patent No. 329,758, dated November3, 1865.

Application'filed September 10. 1885. Serial No. 176,700.

To all whom it may concern:

Be it known'that we, JAMES H. MI'roHELL and WILLIAM T. MITCHELL,citizens of the United States, residing at Vellington, in the county ofSumner and State of Kansas, have invented certain new and usefulImprovements in Adjustable Shades for WVindows, of which the followingis a specification, reference being had therein to the accompanyingdrawings. 7

Our invention relates to adjustable shades for windows; and it consistsin the construction and arrangement of the parts, which will be morefully hereinafter described, and pointed out in the claims.

The object of our invention is to provide a window-shade which is adjustably supported on a window-frame, and which is adapted to be moved upor down, so that the windowsash may be accessible from either the upperor lower portions thereof, or both, whereby the apartment may be readilyventilated without injury to the curtain.

A further objectof our invention is to so construct the sliding supportfor the curtain that it may be readily adjusted to shade either theupper or lower portion of the window, thus allowing the single shade toserve the double purpose, being readily handled and operated andeasily'understood.

WVe attain these objects by the mechanism illustrated in theaccompanying drawings, wherein like letters of reference indicatesimilar parts in the several views, and in which Figure 1 is a frontelevation of a windowframe with our improvement mounted thereon in anormal position, and showing in dotted lines the curtainsupport sliddownward. Fig. 2 is a transverse vertical section of the same with thesliding curtain-support drawn down and the upper sash of the windowlowered for ventilation. I

A indicates the window-frame, which is of ordinary construction and hasa strip, b, on each of its sides on the inside portion thereof andadjacent to the window-sash,which is best illustrated in Fig. 2. Thesestrips 1) are engaged by metal slides b, which are secured to a slidingsupport, B, upon which support (No model.)

the on rtainroller C is mounted, which carries the curtain O. The roller0 may be of any preferred form of construction, and may be operatedeither automatically by springs or by a cord-and-ratchet movement, 0.Upon the upper side of the curtain-support O are mounted suitable wireloops, 0 0, having two "apertures formed therein for the purposeswhichwill be presently described. The upper portion of the window-frameAis provided with two strap-metal boxes, D D, in which are pivoted, as atd, the dogs D D. 2 upper part of these boxes D coiled springs d daremounted,which bear against the upper por- ;tion of the said dogs Dand keep them thrown In the back and the lower ends of the same thrownin the opposite direction. The lower ends of the dogs D are formed inthe shape of ah'ook, LP, and the upper portions thereof with aloop oreye, d The hooks d engage with thelower parts of the divided loops 0,while the upper parts of said loops have cords d fastened thereto, andfrom thence the cords pass up through the loops d in the upper parts ofthe dogs D, "and from thence to and through an eye, A,

secured to the frame A. The cords (1* each pass through the loop A, andare made sufficiently long to be within easy reach of the operator.. Thelower portion of the support B is also provided'with an eye, 0 to whicha cord, 0',

is secured and hangs down to within reaching distance. These cords cland 0 pass down under the curtain O, and may beremoved from the front ofthe window by being fastened to *or thrown over an ornamental cleat,

a, secured to one side of the window-frame. ;To the uppermost side ofthe support B a large -wire loop, B, is secured, which extends outby thedust coming in through the upper part of the window-sash, which may beopen. On

each side of the frame A, in the lower portion thereof, are mounted twostops or guards, a, which limit the downward movement of the support B.These stops may be of suitable fasten the said support in this position.

construction and arrangement, and ornamented in any suitable manner. 1

Having thus described the mechanical construction of ourimproved windowattachment, the operation of the same will be as follows: By pulling thecords d the top portions or loops, d ,of the dogs DD will be drawnagainst the springs d d, and the lower portions or hooks, d, will. bedrawn away from engagement with the divided loops 0, and by pulling thecord 0, attached to the lower portion of the support B, the saidsupport, curtains, and fixtures can be drawn downward, so as to leave aspace above the same either to lower the upper sash and ventilate theapartment or to shade the lower portion of the window and permit theentrance of light through the top of the same. When the support B ispulled up again, by means of the cords d, the

hooks d? of the dogs D D engage the lower portion of the divided loops 0and securely y drawing the support only partially down from the top ofthe window the apartment can be ventilated from above and below at thesame 7 time, or light may be likewise admitted.

g It is obvious that many minor details of construction could be madeand substituted for those shown andidescribed without in the leastdeparting from the nature and principle of our invention.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is'

1. In an adjustable shade for windows, the combination of the slidingsupport carrying the curtain and fixtures, cords for raising andlowering said sliding support,and springactuated dogs, operated by thesupportingcords, to secure and release the said sliding support,substantially as described.

2. In an adjustable shade for windows, the combination of the slidingsupport carrying the'ciirtain and fixtures, divided loops secured to thetop of the said support, spring-actuated dogs engagingthelower portionof the divided loops, cords secured to the upper portions of the dividedloops and passing through loops formed on the upper parts of the saiddogs, and a cord attached to the lower portion of the sliding support,said cords operating to raise or lower the said support, substantiallyas de-' scribed.

'3. In an adjustable shade for windows, the combinationof the slidingsupport carrying the curtain and fixtures, divided loops secured to'thetop of the supporting-frame, spring-actuated dogs engaging in the lowerportion of the divided loops, cords attached to the top portions of thedivided loops and passing through loops in the top of the dogs, an eyeat or near the center of the window-frame through which the two cordspass, a cord attached to the underside of the curtain-support, and stopson divided loops attached to the top of the said. supporting-frame,strap-metal boxes secured to the'window-frame, dogs pivoted thereinhaving loops formed on their upper ends and books on their lower ends,said hooks engaging with the divided loops on the sliding support,coiled springs actuating the dogs, cords attached to the top portions ofthe divided loops and passing through the loops in the I upper portionsof the dogs, an eye in the center of the window-frame engaging thecords,

and a cord attached to the lower portion of the supporting-frame,substantially as'described.
